A private letter from Philadelphia informs us of a very

interesting geolo- gical discovery. About two months ago, Dr. Dickeson of that city had exhumed, near Natchez on the Mississippi, from the depth of one hundred feet below the surface, a fossil human bone. The fossil was examined at a meeting recently held in the house of Dr. Samuel George Morton of Phila- delphia, the eminent ethnologist: Professor Agassiz, Mr. George R. Glid- don, and several other palaeontologists and archaeologists, were present. The fossil was pronounced to be one of the pelvic bones of a man between the ages of sixteen and twenty years. It was found amongst other fossilized remains of the megatherium, megalonyx, and other primeval creatures. The specimen has been deposited in the museum belonging to the Academy of Natural Sciences at Philadelphia.
